ANNA TREXLER, OF SABIN, MINNESOTA.

..COMBINED PLOW AND HARROW.

SPECIFICATION forming part of Letters Patent No. 389,675, dated September 18, 1888.

Application filed October 10, 1887. Serial No. 251,923v (No model.)

To all whom it may concern: 1 Be it known that I, ANNA TREXLER, of Sabin, in the county of Clay and State of Minnesota, have invented a new and Improved Combined Plow and Harrow, of which the following is a full, clear, and exact description.

My invention relates to a combined plow and harrow, and has for its object to provide a simpleinexpensiveharrowattachmentadapted for connection to a plow-beam to be drawn therefrom, and operating to pulverize the earth freshly turned over by the plow, to prepare the soil to receive seed, and accomplish the work with economy of time and labor.

The invention consists in certain novel features of construction of the combined plow and harrow, and of the harrow attachment particu larly, all as hereinafter described and claimed.

Reference is to be had to the accompanying 2o drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan viewof my improved ,plow and harrow. Fig. 2 is a side elevation there- 2 5 of, and Fig. 3 isaperspective view of the draftbar which connects the harrow to the beam.

The plow A may have any approved conerably stayed to each other by a brace-bar, c

0 An ordinary clevis, G, clamps the part c of the draft-bar,by its cross-piece g, to the plow-beam about over the center of the plow mold-board, and so as to allow vertical adjustment of the draft-bar on the plow-beam.

The draft-bar O is provided with a series of holes, H, into any one of which a ring or link, I, may be connected, and to this ring or link is attached a short chain, J, which is connected by a ring or link with a draft-clevis, K, held to the forward end of the harrow by a pin, k,

plow

on which the clevis may be turned horizontally, to allow a pin, L, to be passed through the back end of the clevis into a hole in the beam b of the harrow, as shown in full lines in Fig. 1 of the drawings, or to allow said pin L to be set in a hole, Z, made in the other beam, 1), of the harrow. The forward end of the clevis K is provided with a series of holes, k, into any one of which the ring attached to the chain J, or one of the chain-links, may be coupled. With this construction the harrow may be connected to the draft-bar O nearer to or farther from the plow-beam, and by turning the clevis K and adjusting the pin L in either of the two holes in the barrow-beams b b the line of draft or position of the moving harrow may be regulated at will, to cause the barrow-teeth b to work most effectivelyin crushing and pulverizing the earth thrown over in front of it by the plow mold-board.

The outer end of the draft-bar G is connected by a chain, M, with the forward part of the plow-beam, and when the beam is a wooden one the chain will be connected to it by an eyebolt, N, passed through a metal plate fixed to the side of the beam and held by a nut, as shown in the drawings; but when the plow-beam is made of metal a small clevis will be substituted for the eyeboltto hold the draft-chain M. The plow-beam has the usual clevis, d, allowing the draft-connection to be set higher or lower for working the mold-board at differentdepths in the soil.

, The harrow B has a general form, and comprises the two toothed beams b b, above 85 mentioned, and a toothed beam, b The beams b b are connected to each other at the nose or point of the harrow, and are also connected by cross-bars b 6 and the beam 12 is connected to the beam 12' and the rear crossbar, b all as shown most clearly in Fig. 1 of the drawings.

It is obvious that by raising the draft-bar 0 .on the plowbeam thenose of the harrow will also be raised correspondingly, and this feature, in connection with the adjustment of the 9 harrow nearer to or farther from the plow moldboard and the adjustments of the barrow-clevis on the frame and of the draft-chain J in the clevis, allows the harrow to be set high or low or to take any preferred line of draft over the 103 earth freshly turned over by the plow moldhoard. The draft of the combined implement is light and there is little or no side draft, and economy of time and labor is effected by harrowing while theplowingprogresses, and when the ground is once gone over it is ready to reeeive seed.

Metal rods may be used instead of the chains J M; but the chains are at present preferred.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A. harrow connecting attachment for plows, comprising the L- shape draft-bar O, the horizontal arm 0 of which has apertures or eyes H, and the U shape clip 9, embracing ANNA. TREXLER.
